Abstract
A door lever assembly having a locked and an unlocked position includes a trim housing and a lever handle and cam rotatably connected to the trim housing. A rotatable shaft extends between the lever handle and the cam, with the shaft defining a connection groove therethrough to provide access to a shaft interior. The shaft interior is configured to accept a pin for connecting the cam and the shaft. This pin can be wedgably disconnected following controlled slippage of frictional wedge surfaces in response to excessive force applied to rotate the cam.
